不知道为什么本来能够通过的程序全都出错了 上面是抛出的异常 原因？？？
是不是 因为导入的工程全都是一个名字tomcat 有了相应的处理

又错误
这又是什麽原因呢 为什么？后不运行了

在做QueryStuffTimeRecord 时 出现这种情况 光能出现这句话 “对不起，没有你要浏览的条目” 都觉得改对了 原因是没有把信息送回给页面啊
HttpSession session = request.getSession();
session.setAttribute("stuffTimeRecordList", stuffTimeRecordList);
uesabc1@188.com
在修改和增加混合得页面中 ，为什么attendance是null呢
别的都没有出错是因为你的jsp页面中的问题 下拉列表框的表示应该是
<html:select>
<html:option></html:option>
</html:select>
都丢掉html了
不符合Struts格式了
不知道怎么做的
1 是怎样自动生成的 数据库 类 的
2 是怎样让Log4j控制查看用户的输入信息的
3 多模块开发的要求是怎样又创建的 Struts-config.xml
Web.xml 中是不是要
<param-name> congfig/m10config</param-name>
<param-value>struts-configm10.xml</param-value>
新建 —— File——Struts-config.xml——后出现的标志和已存在的不一样
HttpSession session
Request.getAttribute
Jsp 的用法
